The IOA Division is also considering whether to undertake an investment in the West of the country (the West Project).An initial cash outlay investment of ￡12 million will be required and a net cash inflow amounting to ￡5 million isexpected to arise in each of the four years of the life of the project.The activities involved in the West project will cause the local river to become polluted and discoloured due to thedischarge of waste substances from mining operations.It is estimated that at the end of year four a cash outlay of ￡2 million would be required to restore the river to itsoriginal colour. This would also clear 90% of the pollution caused as a result of the mining activities of the IOADivision.The remaining 10% of the pollution caused as a result of the mining activities of the IOA Division could be clearedup by a further cash outlay of ￡2 million.(c) Evaluate the West project and, stating your reasons, comment on whether the board of directors of NCL plcshould spend the further ￡2 million in order to eliminate the remaining 10% of pollution. (6 marks)(Ignore Taxation).

So Many"Earths"The Milky Way（银河）contains billions of Earth-sized planets that could support life.That's the finding of a new study.It draws on data that came from NASA's top planet-hunting telescope.A mechanical failure recently put that Kepler space telescope out of service.Kepler had played a big role in creating a census of planets orbiting some 170,000 stars.Its data have been helping astronomers predict how common planets are in our galaxy.The telescope focused on hunting planets that might have conditions similar to those on Earth.The authors of a study,published in The Proceedings of the National Academy of Sciences,conclude that between 14 and 30 out of every 100 stars,with a mass and temperature similar to the Sun,may host a planet that could support life as we know it.Such a planet would have a diameter at least as large as Earth's,but no more than twice that big.The planet also would have to orbit in a star's habitable zone.That's where the surface temperature would allow any water to exist as a liquid.The new estimate of how many planets might fit these conditions comes from studying more than 42,000 stars and identifying suitable worlds orbiting them.The scientists used those numbers to extrapolate（推算） to the rest of the stars that the telescope could not see.The estimate is rough,the authors admit.If applied to the solar system,it would define as habitable a zone starting as close to the Sun as Venus and running to as far away as Mars.Neither planet is Earthlike (although either might have been in the distant past).Using tighter limits,the researchers estimate that between 4 and 8 out of every 100 sunlike stars could host an Earth-sized world.These are ones that would take 200 to 400 days to complete a yearly orbit.Four out of every 100 sunlike stars doesn't sound like a big number.It would mean,however,that the Milky Way could host more than a billion Earth-sized planets with a chance for life.This is the first research finding about the planets with a chance for life.A:Right B:Wrong C:Not mentioned

The economy of the United states after 1952 was the econnomy of a well-fed,almost fully employed people. Despit occasional alarms, the country escaped any postwar depression and lived in a state of boom.

The country’s business spent about 30billion dollars for new factories and machinery. National income available for spending was almost a third greater than it had been it had been in 1950. Consumers spent about 256 billion dollars; that is about 700 million dollars a day ,or about twenty-five million dollars every hour , all round the clock. Sixty-five million people held jobs and only a little more than two million wanted jobs but could not find them . Only agriculture complained that it was not sharing in the room. To some observers this was an ominous echo of the mid-1920’s . As farmer’s shre of their products declined , marketing costs rose. But there were , among the observers of the national economy, a few who were not as confident as the majority .

A Debate on the English LanguageA measure declaring English the national language is under intense debate in the United States .The US Senate passed two declarations last week.One calls English the nation's official lan-guage and the other says it is the “common and unifying（统一的）”tongue. But Americans found themselves divided on the issue.Since people worldwide know that most Americans speak only English,many can't understandwhy the issue is so controversial（有争议的）.“The discussion is related to fears of immigration issues,”says Dick Tucker,a social scientist at Pittsburgh's Carnegie Mellon University.“It's related to a worry about the changing demography （人口统计）of the US It's a worry about who will continue to have political and economic influence.”In fact,the notion of protecting the language has been kicked around almost since the nation's founding. John Adams lobbied（游说）in 1780 for the creation of a national academy to correct and improve the English language.But his proposal died,since lawmakers saw it as a roy-alist（保皇主义者）attempt to define personal behavior.Since then,the country hasn't had a national language,but the idea of recognizing the special status of English lived on.The emotions surrounding language resurface（再次浮现）not because people feel comfortable with English .It is more about the discomfort many Americans feel with the new languages,says Walt Wolfram,a professor at North Carolina State University.“Language is never about language,”he says.According to the 2000 US Census Bureau report,of 209 million Americans over 18 years old, 172 million speak only English at home.About 37 million speak languages other than English. Among them,6 .5 million speak poor English and 3 .1 million don't speak English at all. Which statement is true according to the 2000 US Census Bureau report?A: 172 million Americans speak only English in their workplaces.B: 37 million Americans speak English.C: 209 million Americans are above the age of 18.D: 6.5 million Americans speak good English.

问答题Passage 1 The cost of staging the year 2000 Olympics in Sydney is estimated to be a staggering $ 9 million, but (1) the city is preparing to the financial benefits that come from holding such an international event by equaling the commercial success of Los Angeles, the only city yet to have made a demonstrable profit from the Games in 1984. At precisely 4:20 a.m. on Friday the 24th of September 1993, it was announced that Sydney had beaten five other competing cities around the world, and Australians everywhere, not only Sydneysiders, were justifiably proud of the result. (2) But, if Sydney had lost the bid, would the taxpayers of New South Wales and of Australia have approved of governments spending millions of dollars in a failed and costly exercise? There may have been some consolation in the fact that the bid came in $ l million below the revised budget and $ 5 million below the original budget of $ 29 million formulated in mid-1991. However, the final cost was the considerable sum of $ 24 million, the bulk of which was paid for by corporate and community contributions, merchandising, licensing, and the proceeds of lotteries, with the NSW Government, which had originally been willing to spend up to $ 10 million, contributing some $ 2 million. (3) The Federal Government’s grant of $ 5 million meant, in effect, that the Sydney bid was financed by every Australian taxpayer. Prior to the announcement of the winning city, there was considerable debate about the wisdom of taking financial risks of this kind at a time of economic recession. (4) Others argued that 70% of the facilities were already in place, and all were on government-owned land, removing some potential areas of conflict which troubled previous Olympic bidders. The former NSW Premier, Mr. Nick Greiner, went on record as saying that the advantage of having the Games… “is not that you are going to have $ 7.4 billion in extra gross domestic product over the next 14 years.” (5) I think the real point is the psychological change, the gaining of confidence, apart from the other more obvious reasons, such as the building of sporting facilities, tourism, and things of that nature.
